Question

detremin 5,15,4,16 are in proportion​

Answer 1

No they are not in proportion

Step-by-step explanation:

Sum of means = Sum of extremes

We have to add the first and last numbers which are extremes and we have to add the two numbers in the middle which are called means.If their sums are same then they are in proportion.

= 5+16

= 15+4

= 21

= 15

Since their sums are not equal they are not in proportion.
